Stent crimping mechanisms

a crimping mechanism and stent technology, applied in the direction of prosthesis, forging/pressing/hammering apparatus, shape tools, etc., can solve the problems of reducing the life of fingers, stent and/or iris fingers may be damaged, and so as to reduce the number of blade “gaps” and the effect of reducing the possibility of pinching or damaging the sten

Abstract

A system for reducing the diameter of a stent comprises a stent contracting assembly. The assembly comprises a plurality of blades, which define a diameter reduction chamber. The chamber has an open diameter configuration and a closed diameter configuration. The plurality of blades comprises active blades and floating blades, wherein each active blade is engaged to an actuation mechanism. The actuation mechanism is constructed and arranged to move each active blade from the open diameter configuration to the closed diameter configuration. Each floating blade is moved from the open diameter configuration to the closed diameter configuration only as a result of the movement of the active blades.

[0001] Not Applicable STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH

[0002] Not Applicable BACKGROUND OF THE INVENTION

[0003] 1. Field of the Invention

[0004] The present invention relates generally to stents, stent loading, stent contracting and stent delivery systems and their respective methods of use. Some embodiments of the invention are more specifically directed to stent loading and crimping systems and their methods of use.

[0005] 2. Description of Related Art

[0006] A stent is a generally tubular device that is used to support a bodily lumen. A stent is typically delivered to a desired bodily location via a catheter. Often the stent is loaded onto a portion of the catheter, such as a balloon or other region of the catheter shaft. In some stent delivery systems the stent is crimped to the catheter in order to minimize the profile of the stent on the catheter and to prevent undesired movement of the stent relative to the catheter shaf...
